DANIEL STANISLAS LAGASSE, OF LYNN, MASSACHUSETTS.

FASTENER FOR SHUTTERS.

Application filed April 12, 1912.

To all whom it may concern Be it known that I, DANIEL STANISLAS Liienssn, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Fasteners for Shutters, of which the following is a specification.

This invention is an improvement in fasteners for shutters, blinds, or the like.

One object of this invention is to provide a fastener for the above purpose which cannot be unlocked from the outside when the shutter is closed.

Another object is to provide a fastener which will secure the shutter rigidly in either open or closed position and which is strong enough to withstand the rough usage to which such articles are subject.

The features of the invention will be best understood from the following description and the accompanying drawings, in which Figure 1 is a view showing the improved fastener attached to a shutter or blind, which is closed; Fig. 2 is an isometric view of the fastener detached from the shutter and window casing; Fig. 3 is a section on the line 33 of Fig. 2; Fig. 4 is a detail view showing the manner of engaging the catch to secure the shutter in an open position; and Fig. 5 is a detail View of the catch shown in Fig. 4.

In the preferred form of this invention which is illustrated in the drawings, this fastener comprises a latch carrying portion which is attached to a shutter 2, a catch 3 fixed in the sill 1 for holding the shutter in a closed position and a second catch 4 for holding the shutter in an open position. The latch carrying portion consists of a plate 5 preferably formed from sheet metal and having a depending flange 6. On the side of the plate opposite the flange 6 there is an ear 7 formed by bending down a projecting portion of the plate 5. A. latch 8 of sheet brass or other resilient material is secured to the ear 7 by a rivet 9. The latch is bent at an angle so as to have a free end projecting through an opening 10 in approximately the middle of the flange 6. The projecting end of the latch is bent back on itself to form a hook 11 as is shown in Fig. 2. The latch is inclosed between the flange 6 and the ear 7 by a box 12. This box is preferably formed from a rectangular piece of sheet metal bent into the form shown Specification of Letters Patent.

most plainly in Figs. 1 and 2, having an extending flange 13 on each side of the box. The box is secured in place by screws 14 which also serve to hold the plate 5 to the lower bar of the shutter, screw holes 15 being provided in the plate and box for this purpose.

The plate 5 is attached to the lower part of the shutter 2 with the flange 6 about flush with the inner face of the shutter. The catch 8 is driven into the window sill 1. The upper end of the catch is bent over in a substantially horizontal plane and is provided with a notch 17 which is adapted to engage the hook 11 on the latch 8 when the shutter is closed.

It is apparent from Fig. 1 that the flange 6 renders it impossible for any person desiring to open the shutter from the outside, to reach the hook 11 which must be released from the catch 8 before the shutter can be opened. It is also evident from Fig. 3 that, when in this position, the shutter cannot be lifted to unhinge it from the wall of the building, the bottom of the box 12 preventing this by engagement with the bottom of the catch 3.

The catch 4 is secured to the wall of the building in such a position that when the shutter 2 is swung about its hinge 18, the catch. will enter a hole 19 in the flange 6. The catch is made of a suitable spring material and is provided at its outer end with a slot 20. The portion 21 in front of the slot is bent to one side so as to present an inclined surface over which the flange 6 may pass, the spring of the material being employed to return the catch toward its normal position, thereby holding the flange 6 in the slot 20. The portion 22 of the catch directly behind the slot 20 is bent in a similar manner to the front portion but is somewhat longer so as to form an abutment for the flange 6 as clearly shown in Fig. 4.

The object in providing a hole in the flange for the catch 4 instead of allowing the catch to engage an edge of the flange is to prevent the shutter from being lifted, as might sometimes happen in a severe storm, and unhinging itself. By the construction contemplated in the present invention, the shutter is restrained from lifting by the lower edge of the hole 19 engaging the catch 4 as is illustrated in Fig. 4.

This invention has been described as embodied in a fastener for shutters or'blinds;

it is not, however, limited in its uses to such forms of closures but may also be employed in fastening other forms of swinging coverings for openings.

It is to be understood that the invention is not limited to the construction and arrange ment of parts herein set forth but is capable of wide variation without departing from the spirit of the invention as defined in the appended claims.

What is claimed as new, is 2- 1. A shutter fastener, having, in combination, a plate carried on the shutter, an ear depending from the plate on the outside of the shutter, a latch mounted on the ear and extending toward the inside of the shutter, a flange depending from the plate on the inside of the shutter and provided with an opening for the latch, a box toinclose the sides and bottom of the latch, and a catch to engage the latch when the shutter is closed.

2. A shutter fastener, having, in combination, a catch to secure the shutter in open position, a catch to secure the shutter in closed position, a plate carried on the shutter, an ear depending from the plate on the outside of the shutter, a latch mounted on the ear and extending toward the inside of the shutter, a flange depending from the plate on the inside of the shutter and provided with an opening for the latch and an opening for the first named catch, a box to inclose the sides and bottom of the latch,

and single means for securing the box and plate to the shutter.

3. A shutter fastener having, in combination, a catch to hold the shutter closed, a plate forming an extension to the bottom of the shutter and provided with an opening to receive the catch, a latch carried by the shutter and coacting with said catch, a casing to inclose the latch on all sides except toward the inside when the shutter is closed and acatch constructed to engage the plate to hold the shutter in open position.

4. A shutter fastener having, in combination, a catch mounted on the window sill, a plate carried by the shutter provided with a catch-receiving opening and extend-- ing from the bottom edge of the shutter substantially to the window sill, a casing to inclose the catch when the shutter is closed, and a latch mounted inside the casing to coact with the catch.

5,. A shutter fastener comprising a plate attached to the shutter having a depending flange 6 provided with openings 10 and 19, a box 12 to form an inclosure back of the opening 10, a latch 8 mounted inside of the box, a catch 3 to coact with the latch S and a catch 4 to coact with the flange 6 adjacent the opening 19, substantially as described.

In testimony whereof, I have afiixed my signature, in the presence of two witnesses.
